Passementerie - Trimmings, from Provencal: passamen, Spanish: pasamiento, and Italian: passamento.
Trims are as ancient as we are. Inhabitants of the Alleutian islands made passementerie from seal whiskers strung with pearls. Kumihomo, a Japanese braiding process, is a relative. But at no time have there been persons devoted exclusively to trim making. From the Middle Ages to the present passementiers were also blondiers/dyers, crepiniers/fringe makers, boutonniers/button makers, and until the 17thc, lace makers.
